The
option
is selected from one
of the
m4
option names shown in the leftmost column of
Table 34.3
.
The
value
is an appropriate value for that option, as
described in the reference section of this chapter. Note that
the
option
and the
value
should each be enclosed in
opposing
half-quotes
to prevent
m4
from wrongly recognizing either as a keyword or macro.
The leftmost half-quote is the reverse apostrophe, and the
rightmost is the normal apostrophe.
